ABSTRACT:
A hollow cooled airfoil includes an array of radially-spaced apart, longitudinally-extending partitions defining a plurality of cooling channels therebetween. A plurality of aft pins are disposed in at least one of the cooling channels. Elongated turbulators are disposed in at least one of the cooling channels, and are oriented at an angle to a longitudinal axis of the vane such that an aft end of each of the turbulators is closer to an adjacent partition than a forward end of the turbulator. The vane includes an array of radially-spaced apart, alternating longitudinally-extending lands and longitudinally-extending dividers which define plurality of trailing edge slots therebetween. Each of the trailing edge slots has an inlet in fluid communication with a trailing edge cavity and an axially-downstream exit in fluid communication with the vane's trailing edge. The dividers have an axial length less than an axial length of the lands.
